Description
TECHNICAL FIELD
[0001] Various embodiments described herein relate to a display for
a gaming machine. More specifically, the display includes a first
spinning portion and a second spinning portion which spin at
different angular velocities. The ring can be backed by an liquid
crystal display (LCD) and the motion caused by a clockwork
mechanism, or Geneva wheel.
BACKGROUND
[0002] Gaming devices, such as slot machines and video poker
machines, provide fun and excitement to the player. Gaming, in
general, provides an escape from the everyday rigors of life.
Gaming devices use bright lights and exciting sounds to have the
gaming machines stand out from other gaming machines. Gaming
devices, in particular, use one or more displays that enable the
player to see and play the game. The displays typically portray the
action of the game and ultimately indicate whether or not the
player wins and how much the player wins.
[0003] The quest for gaming instrumentalities which will provide
greater game interest and entertainment among players who wager is
an ongoing odyssey. Greater game interest translates into greater
revenues for the owners of the games. More interest translates into
more money wagered on a machine over time. A popular game will stay
on a gaming floor for a longer amount of time since the game owner,
such as a casino, will get more revenue from a popular game. Even
popular games can have a drop off in popularity over time. New
games or improved games generally enjoy a time of increased
popularity. Therefore, the industry always seems to seek different
ways of making even popular games have some level of newness. This
piques players interest in the game so that it will draw high
number of players while it has the new feature. If a new feature is
introduced periodically, the overall numbers of players can be
increased over a given time period. Increased numbers translates
into increased revenue to the owner of the particular game.
Different features or different displays or different aspects of
game play can be introduced periodically to keep even popular games
fresh and new and keep the players interested in coming to play a
particular game.
[0004] In the recent past, most new games are based on video
displays. The advent of the computer and the video monitor expanded
the possibilities for gaming devices. There are now video poker,
video blackjack and other types of video gaming machines. Video
displays are popular and very versatile as any number of games can
be offered by merely rendering the game on the video display. There
is one phenomenon that is contrary to continually introducing brand
new features on a video game. There is a nostalgic movement that
provides appeal for some game players. Therefore, sometimes
changing a game to include an old aspect or nostalgic feature also
appeals to players and can be another way to introduce a change
that attracts players to a game. One prime example is video slot
machines. Reels were used in early "one-armed bandits". To appeal
to certain players, sometimes reels are rendered on video displays
that replicate the reels. Some new video slot machines even include
actual "old-time" reels and a handle to pull to cause the reels to
move.
[0005] In addition to introducing new features or new game play to
keep a game fresh, there are also other ways to maintain interest
in a game. For example, bonus games attract and keep players at a
gaming machine. As a result, bonus games in gaming machines have
become much more prevalent and elaborate in recent years. The bonus
game is typically a gaming machine or a random selection device
having a gaming play that is enabled by a bonus qualifying signal
from an underlying or primary gaming machine. Bonus games include
an additional game feature contained within a single gaming
machine. For example, in slot machines, video monitors have also
been used to provide bonus or secondary games. Players play the
base game of slot until becoming eligible for a bonus game. The
base game temporarily pauses, while the player plays the bonus
game. When the player completes the bonus game, the gaming device
returns the player to the base game.
[0006] Accordingly, providing a gaming device that may use a video
monitor, which provides increased flexibility to the gaming device
to add more symbols and more elaborate bonus games, while providing
some aspect of the gaming device that is mechanical and provides a
fun and exciting mechanical display is desirable.

DETAILED DESCRIPTION
[0020] In the following paper, numerous specific details are set
forth to provide a thorough understanding of the concepts
underlying the described embodiments. It will be apparent, however,
to one skilled in the art that the described embodiments may be
practiced without some or all of these specific details. In other
instances, well known process steps have not been described in
detail in order to avoid unnecessarily obscuring the underlying
concepts.
[0021] FIG. 1 is a perspective view of a bank 101 of slot machines
on a casino floor, at least one of which includes an example
embodiment of the invention. As shown in FIG. 1, the bank of slot
machines includes a plurality of electronic gaming machines 100.
Generally, an electronic gaming machine 100 encloses the computer
system 2604 (gaming device shown in FIG. 9) and additional
components which may or may not be coupled to the computer and
under computer control, according to an example embodiment. The
individual gaming devices can be attached to a network 2601. Also
attached to the network 2601 is a server 2602. The server 2602, the
gaming device 2604 and other devices attached to the network 2601
form a gaming system 2600. Such gaming systems can be found on many
gaming floors in casinos and elsewhere. The gaming system 2600 can
include a number of gaming machines in a progressive game with
progressive jackpots.
[0022] The gaming machine 100 includes a housing 110 which has a
top box 112 and a cabinet enclosure 190. The housing 110 also
includes a specialized keyboard 114, which is also termed a player
switch panel which is accessible to the player. The player makes
wagers and controls certain aspects of play through the player
switch panel 114. The housing 110 includes a first display 120 and
a second display 200. The first display 120 is for the primary game
of the electronic gaming machine 100. The first display or monitor
120 displays many of the main aspects of the game as the game is
played. In the embodiment shown, the first display or monitor 120
includes a number of reels associated with a slot machine. The
reels can be actual reels or can be graphical renderings of reels.
The player switch panel 114 includes buttons for interaction by the
user with the electronic gaming machine 100. The buttons can be
used to set a bet and also determine a number of lines to bet as
well as a wager amount. As shown in FIG. 1, the electronic gaming
machines include a wheel of fortune theme. It should be noted that
the wheel of fortune type machine is only one type of machine that
can use the invention. The user interacts mainly with the first
monitor 120 during game play.
[0023] The second monitor 200 can also display some of the aspects
of the game as played. In some embodiments, the second monitor or
display 200 is used for displaying or playing a bonus game. A bonus
game is another game related to the first game. The bonus game can
be thought of as a game within a game. Both monitors 120, 200
display graphics for attracting players while the game is not being
played. The display 200 includes a first rotating portion 210 and a
second rotating portion 220. The first rotating portion 210
includes a first or inner rotating wheel 211 and the second or
outer rotating wheel 212. The inner rotating wheel 211 and the
outer rotating wheel 212 are attached to one another and rotate at
substantially the same angular velocity. The second rotating
portion 220 is a ring which is positioned between the first
rotating wheel 211 and the second rotating wheel to 212. As shown
in FIG. 1, the bank 101 of electronic gaming machines 100 includes
only a single machine includes the second display 200.
[0024] Many computer components are within housing 110 such as a
central processor on a mother board, a communication board
assembly, an input/output board, a power supply, and a DC
communication board assembly, and a DC distribution board assembly.
Some of these components are for a typical computer system, such as
the one described below in FIG. 9. The housing 110 also includes
other components that are not part of the computer system 900
(shown in FIG. 9) but are part of the EGM 100 or the gaming system
2600.
[0025] FIG. 2 shows a perspective view of the display 200 from an
electronic gaming machine 100, according to an example embodiment.
FIG. 2 shows the display 200 which will now be further detailed.
The display 200 includes a glass or plexiglass background 230. The
background 230 includes graphics and is back lighted. The graphics
shown in FIG. 2 are for a wheel of fortune display 200. It should
be noted that the invention is not related to a particular theme or
to a particular game but can be used with any particular game or
theme. The display 200 also includes a chase ring 240. The chase
ring 240 includes lights which are sequentially lit as the primary
rotating portion 210 rotates. The lights within the chase ring 240
appear to be chasing the rotation of the first rotating portion
210. The display 200 also includes a pointer indicator 250. The
pointer indicator 250 is backlit, and this example embodiment. The
display also includes the first rotating portion 210 and the second
rotating portion 220. The first rotating portion 210 includes an
inner wheel 211 and an outer wheel 212 which are connected to one
another. Thus the inner wheel 211 and the outer wheel 212 rotate at
the same or substantially the same angular velocity. A set of webs
connect the inner wheel 211 the outer wheel 212. As shown in FIG.
2, webs 213, 214, 215, and 216 connect the inner wheel 211 and the
outer wheel 212. The inner wheel 211 and the outer wheel 212 and
the webs 213, 214, 215, and 216 form the first rotating portion
210. The second rotational or rotating portion 220 rotates at a
different angular velocity from the first rotating portion 210. The
second rotating portion 220 is transparent. One or more displays
can be placed behind the second rotating portion 220. The one or
more displays can be seen through the second rotating portion 220.
As shown in FIG. 2, therefore LCD or liquid crystal displays
positioned behind the second rotating portion 220. Two of the LCDs
show a set of reels associated with a slot machine. Another LCD
shows a set of numbers. And yet another LCD shows a pattern that
also includes numbers. In one embodiment, four separate LCDs are
positioned behind the second rotating portion 220. In another
embodiment a single LCD is placed behind the second rotating
portion and is divided into separate display areas. Four display
areas are shown in FIG. 2. It should be noted that any number of
display areas can be placed behind the transparent second rotating
portion 220.
[0026] The primary rotating portion 210 is connected to a hub 260.
The primary rotating portion 210 rotates about the hub 260. The hub
260 includes a hub cap 262. The second rotating portion 220 also
includes a set 270 of four driven indicators or fans 271, 272, 273,
274. The four driven indicators are fans 271, 272, 273, 274, can
also be used to show different aspects of a game associated with
the electronic gaming machine 100. In one example embodiment, the
second rotating portion 220 and the LCD display are displays
located behind the second rotating portion 220 are used to display
a certain aspects of a bonus game. Should be noted however, that
certain aspects of the bonus game can be displayed or it can be
part of the primary game in still be encompassed as part of the
invention.
[0027] The primary rotating portion 210 is in this really
accelerated to a substantially angular velocity and then
decelerated to indicate a "spin". The primary rotating portion 210
is stopped by the deceleration. When the primary rotating portion
210 is stopped, a value is positioned below the pointer indicator
250. As the primary rotating portion 210 is rotated to indicate a
spin, the secondary rotating portion 220 is rotated at different
angular velocities with respect to the primary rotating portion
210. The respective motions of the first or primary rotating
portion 210 and the secondary rotating portion 220 can be
accomplished with separate drivers or drive motors. In the example
embodiment shown in FIG. 2, the respective motions of the first or
primary rotating portion 210 and the secondary rotating portion 220
are accomplished mechanically. In other words, the drive mechanism
for the primary rotating portion 210 can be used to also drive the
secondary or second rotating portion 220.
[0028] FIG. 3 is a graph showing the angular velocity of the
primary rotating portion 210 of a display 200 and showing the
angular velocity of the secondary rotating portion 220 of a display
200 through the course of a spin on the electronic gaming machine
100, according to an example embodiment. The angular velocity of
the primary rotating portion 210 is shown by the dotted line 300.
As shown by the dotted line 300 the primary rotating portion 210 is
initially accelerated and then has a substantially constant angular
velocity for an amount of time and then decelerates until the
angular velocity is zero. The angular velocity of the secondary
rotating portion 220 is shown as solid line 320. As is shown in the
graph, the angular velocity of the secondary rotating portion 220
varies with respect to the angular velocity of the first rotating
portion 210. In other words, through the course of a spin, the
angular velocity of the secondary rotating portion 220 is generally
different than the angular velocity of the first rotating portion
210. At sometimes it is slower and other times it is greater than
the angular velocity of the first rotating portion 210. Of course,
when rotation starts and when rotation ends both the first rotating
portion and the second rotating portion are also at zero velocity.
In some embodiments, one of the first and second rotating portion
may be stopped while the other of the first and second rotating
portions may continue to spin until it to stops. In other words,
the first rotating portion 210 and the second rotating portion 2202
not have to stop at substantially the same time. One of the first
rotating portion 210 or the second rotating portion 220 can lag the
other in terms of starting or stopping their respective
rotation.
[0029] FIG. 4 is a view of a single Geneva wheel 300 driven by a
drive wheel 310, over time, according to an example embodiment. The
motion of the first rotating portion 210 and the second rotating
portion 220 can be achieved mechanically by using one or more
Geneva wheels 300 driven by a drive wheel 310. FIG. 4 shows a drive
wheel 310 that includes a drive pin 312 driving a single Geneva
wheel 300. The motion of a single Geneva wheel driven by the drive
wheel is first described here. The motion of several or a plurality
of Geneva wheels 300 being driven by a drive wheel 310 will be
discussed with respect to FIG. 6. A single Geneva wheel 300 is
first described with respect to FIG. 4 for the sake of simplicity.
The drive pin 312 is positioned near the outer edge of the drive
wheel 310. A single Geneva wheel 300 is shown in various positions
as it is driven by the drive pin 312 at times t.sub.1, . . .
t.sub.4. The Geneva wheel 300 includes a plurality of elongated
slits 321, 322, 323, 324. The plurality of elongated slits 321,
322, 323, 324 are along radials from the center of the Geneva wheel
300. In this example embodiment the elongated slits 321, 322, 323,
324 are substantially perpendicular to one another. The Geneva
wheel 300 is rotates about a central axis 340. The Geneva wheel 300
can be attached to a secondary rotating portion 220 while the first
rotating portion 210 is driven by the drive wheel 310. The Geneva
wheel 300 is rotatably mounted so that the slit 321 can be
positioned to be substantially tangent to the circular path
associated with the drive pin 312. As shown at time t.sub.1, the
drive pin 312 winters the slit 321. The pin 312 enters the slit 321
and the pin 312 proceeds down a portion of the length of the slit
321. The pin 312 progresses along its circular path and drives
against one edge of the slit 321 and moves or rotates the Geneva
wheel 300 in a counterclockwise direction as depicted by the arrow
about the axis 340 of the Geneva wheel. At time t.sub.2, the drive
pin 312 has progressed down substantially the length of the slit
321 and the drive pin 312 is placing a force on sidewall 321a of
the slit 321. At time t.sub.3, the drive pin 321 continues to drive
against the side wall 321a until the slit 321 is again parallel
with another tangential line to the circular path of the drive pin
312. At time t.sub.4, the drive pin 312 has exited the slit 321 and
the slit 321 is positioned along a line tangential to the circular
path of the drive pin 312. At this point, the drive pin 312 and the
drive wheel 310 have passed through approximately 100.degree. of
rotation. The rotation has been in a clockwise direction. The
Geneva wheel 300 has been driven substantially 90.degree..
Initially the slit 321 was positioned along a tangential line to
the path of the drive pin 312. After the Geneva wheel is driven
90.degree., the next slit 322 on the Geneva wheel 300 is now
positioned on the same or substantially the same tangential line
and is ready to receive the drive pin 312. This process repeats
with every rotation of the drive wheel 310. The drive pin 312
drives the Geneva wheel 300 via successive slits 321 322, 323, 324.
The drive wheels 310 can move out a substantially angular velocity
and produce a varied angular velocity rotational output to a body
connected to the Geneva wheel 300. For example, as the drive pin
and initially enters the slit 321 the Geneva wheel is substantially
still. As the drive pin 312 passes down the slit 321, the drive pin
eventually acts upon the sidewall 321a and begins the rotation of
the Geneva wheel 300. As the force on the sidewall 321a becomes
larger the rotational velocity of the Geneva wheel increases until
maximum velocity is reached at approximately the time that the slit
321 is on a radial line from the center axis of the drive wheel
310. Further rotation causes the drive pin to continue placing a
force on the sidewall 321 until the slit 321 is positioned along a
second tangential line to the circular path of the drive pin
312.
[0030] FIG. 5 is a top view of a drive motor 310 interacting with a
plurality of Geneva wheels, 300, 510, 520, and 530, as part of a
display 200 for an electronic gaming machine, according to an
example embodiment. FIG. 5 is a view of the display 200 from the
backside of the display as shown in FIG. 2. Actually only the
rotating portions of the display are shown. The display includes a
primary rotating portion 210 which has an inner wheel 211 and an
outer wheel 212. The display 200 also includes a secondary rotating
portion 220. The inner wheel 211 and the outer wheel 212 rotated
substantially the same angular velocity. The drive wheel 310 is
connected to the inner wheel 211 of the primary rotating portion
210. The drive wheel 310 includes drive pin 312. As the drive wheel
310 rotates and drives the primary rotating portion 210, the drive
pin 312 interacts with and drives the Geneva wheels 300, 510, 520,
and 530. The pin 312 initially enters a slit 321 on the Geneva
wheel 300. The Geneva wheel 300 is attached to a connecting arm 550
which is attached at one end to the secondary rotating portion 220.
The free end of the connecting arm 550 carries the Geneva wheel
300. As the pin 312 travels over its circular path it drives the
Geneva wheel 300 in the same manner as described in FIG. 4. As the
pin exits slot 321 (such as is shown in FIG. 4), the pin enters a
slit in the Geneva wheel 510. The slit in the Geneva wheel 510 is
positioned along a path tangential to the circular path of the
drive pin 312. The Geneva wheel five can then moves in the same
fashion or similar fashion as the Geneva wheel 300 in FIG. 4. The
Geneva wheel 510 is attached to a connecting arm 552. The
connecting arm 552 is attached at its other and to the secondary
rotating portion 220. The connecting arm 554 is connected to the
secondary rotating portion 220 and is also connected to Geneva
wheel 520. As the drive pin 312 leaves the Geneva wheel 510 it
enters a slit in the Geneva wheel 520. Again the same or similar
motion is imparted on the Geneva wheel 520 as the Geneva wheel 310
in FIG. 4. A connecting arm 556 is also connected to the secondary
rotating portion 220 and to a Geneva wheel 530. When the drive pin
312 leaves the Geneva wheel 520 and enters into a slit in Geneva
wheel 530. The end result is a motion in which the secondary
rotating portion 220. As can be seen, that a single drive motor or
driver 310 can be used to drive both the primary rotating portion
210 and the secondary rotating portion 220. The drive wheel 310
interacts with successive Geneva wheels 300, 510, 520, and 530 as
the drive pin 312 travels along this circular path. The motion
imparted on the Geneva wheels 300, 510, 520, 530 is transferred to
the secondary rotating portion 220 by the connecting arms 550, 552,
554 and 556. The motion that results is similar to that described
above and shown in the graph of FIG. 3.
[0031] FIG. 6 is a perspective view of a backside 600 of the
display shown in FIG. 2, according to an example embodiment. The
backside 600 of the display 200 shows liquid crystal displays 610,
612, 614 and 616. The liquid crystal displays 610, 612, 614, 616
are arrayed around the center of the display or around the drive
wheel 310. The drive wheel 310 is driven by drive motor, not shown.
The drive motor may be within the drive wheel 310, in some
embodiments. The backside 600 of the display also includes a main
wheel motor bracket 620. The drive wheel 310 fits within the main
wheel motor bracket 620. The drive pin 312 faces the LCD displays
610, 612, 614, 616 as it travels over its circular path. Geneva
wheels, such as Geneva wheel 300, are attached or affixed so that
they can engage the drive pin 312 and in part the motion previously
discussed to the secondary rotating portion 220 (shown in FIG. 2).
The Geneva wheels are not shown in FIG. 6. The main wheel motor
bracket 620 also includes several fixed shaft bearings, such as
bearings 622, 624, 626. The Geneva wheels, such as Geneva wheels
300, 510, 520, 530 are connected to the fixed shaft bearings 622,
624, 626 and one not shown. The backside also includes several
light emitting diode boards 632, 634, 636, 638. The light emitting
diode boards 632, 634, 636, 638 provide a light between the
sections of the secondary rotating portion 220 (shown in FIG. 2).
Also shown on the backside 600 are the connecting arms 550, 552,
554, 556. As shown and discussed above, one drive wheel 310 having
a drive pin 312 can impart the rotary motion discussed above on the
first rotating portion 210 and on the second rotating portion 220.
It should also be noted that the first rotating portion 210 can be
driven separately from the second rotating portion 220 using two
drive motors. To achieve the motion described above, the drive
motor for driving the second rotating portion 220 would have to be
programmed to produce a variable velocity with respect to the
angular velocity of the first rotating portion 210.
[0032] This concept combines several different aspects of our wheel
products with some new effects. By combining a Geneva wheel
mechanical watch drive mechanism with spinning wheel type devices
new effects can be achieved with very low cost. Implementing LCD
backgrounds into the device matches up a mechanical with newer
display technology. One advantage at the Geneva wheel mechanism is
that only one source of energy is needed to drive several rotating
items, such as the first rotating portion 210 and the second
rotating portion 220. In one example embodiment, this type of
mechanism to produce rotating effects and combinations of pointers.
The Geneva drive is a center drive gear mechanism that translates a
continuous rotation into an intermittent rotary motion. As
discussed above, the rotating drive wheel has a pin that reaches
into a slot of the driven wheel advancing it by one step per full
rotation of the main drive. The drive wheel also has a raised
circular cam blocking disk that locks the driven wheel in positions
between steps. This stepper type motion can be achieved in many
combinations of rotation by how many wheels are connected to the
main drive and how many drive slots are used in the driven
wheel.
[0033] In this example for every full rotation of the main wheel
four secondary wheels rotate as well. The secondary wheel could be
used for effects, as pointers for game awards, or bonus triggers.
Since the wheels are clocked to the main drive their locations are
game predictable depending on the revolutions per minute of the
main wheel. This allows the pointer wheels to line up with any
graphical display content on the LCD background.
[0034] The combinations of driven wheels to drive shaft can be
varied to achieve different results. If the final design is
carefully planned the design could be easily retrofitted from a two
wheel system to a four wheel system etc. All this would take would
be the creation of wheel kits featuring the different combinations,
a new drive cam, and new game software. This provides a future set
of paths for visual electronic gaming machine upgrades. With such a
future set of paths, an electronic gaming machine can be upgraded
well into the future so that the games are continually renewed or
refreshed to keep a high level of interest in particular games
amongst various players.
[0035] FIG. 7 is a flow diagram of a method 700 for moving a first
rotating portion with respect to a second rotating portion of a
display of an electronic gaming machine, according to an example
embodiment. The method 700 for display of a game includes driving a
primary rotating device with a drive mechanism 710, attaching at
least one Geneva wheel to a secondary rotating device 712, and
driving the secondary rotating device using a pin on the drive
mechanism 714. The pin on the drive mechanism is positioned to

wheels are driven with the pin on the drive mechanism. The
secondary rotating device includes at least one window. A secondary
display is placed in a position for viewing through the window of
the secondary rotating device. Driving the primary rotating device
includes rotating the primary rotating device at a first angular
velocity and driving the secondary rotating device includes
rotating the secondary device at an angular velocity which differs
from the first angular velocity during portions of the
rotation.
[0036] FIG. 8 is a flow diagram of another method for moving a
first rotating portion with respect to a second rotating portion of
a display of an electronic gaming machine, according to an example
embodiment. The method 800 for displaying a game includes driving a
primary rotating device with a drive mechanism 810, and driving a
secondary rotating with the drive mechanism 812. The primary
rotating device is driven 810 at a first rate and the secondary
rotating device is driven 812 at a rotating rate different from the
first rate during at least a portion of the rotation. The secondary
rotating device includes at least one window. The primary rotating
device includes an inner wheel and an outer wheel. The secondary
rotating device includes a ring positioned between the inner wheel
and the outer wheel.
[0037] A gaming display includes a primary rotating portion and a
secondary rotating portion. A drive mechanism for driving the
primary rotating portion includes a pin. A Geneva wheel mechanism
is attached to the secondary rotating portion. The pin of the
rotary drive mechanism engages a slot in the Geneva wheel mechanism
to drive the secondary rotating portion at a different angular
velocity than the primary rotating portion. The gaming display
apparatus includes a secondary display situated behind at least one
of the first rotating portion and the second rotating portion, at
least one of the first rotating portion and the second rotating
portion having a window therein for viewing at least a portion of
the secondary display. In one embodiment, the secondary rotating
portion includes a plurality of Geneva wheels attached to the
secondary rotating portion. The plurality of Geneva wheels are
positioned to engage the pin on the driving mechanism. The
plurality of Geneva wheels are attached at a substantially equal
distance from the center of the second rotating portion at
different circumferential positions on the second rotating portion.
The gaming display apparatus also includes at least one liquid
crystal display positioned to be viewed through at least a portion
of the secondary rotating device. The primary rotating portion
includes an inner wheel and an outer wheel that are separated. The
inner wheel rotates at substantially the same angular velocity as
the outer wheel. The inner wheel and the outer wheel are attached
to one another. The inner wheel and the outer wheel rotating at
substantially the same angular velocity, while the second rotating
portion rotates at different angular velocities when compared to
the inner wheel and outer wheel.
[0038] A gaming display apparatus includes a primary rotating
device and a secondary rotating device. The gaming display
apparatus also includes a rotary drive mechanism attached to the
primary rotating device. A Geneva wheel mechanism is attached to
the secondary rotating device. The rotary drive mechanism includes
a pin for engaging the Geneva wheel mechanism. The pin and the
Geneva wheel mechanism drive the secondary rotating device. The
secondary rotating device includes a transparent portion. A
secondary display is positioned behind the primary and secondary
rotating portions and is viewable through the transparent portion.
In one embodiment, the secondary display is at least one liquid
crystal display positioned to be viewed through at least a portion
of the secondary rotating device. In one embodiment, the secondary
rotating device includes a plurality of Geneva wheels attached to
the secondary rotating device. The pin of the rotary drive
mechanism drives the plurality of Geneva wheels attached to the
secondary rotating device. The primary rotating device includes an
inner wheel and an outer wheel. In an embodiment, the inner wheel
and the outer wheel are separated. The inner wheel and the outer
wheel can also be attached to one another so that the inner wheel
and the outer wheel rotate at substantially the same angular
velocity. The secondary rotating portion, in some embodiments, is a
ring positioned between the inner wheel and the outer wheel of the
primary rotating device. The gaming display can also include a
chase light positioned around the primary rotating device. The
rotary drive mechanism includes a stepper motor.
[0039] FIG. 9 is a schematic block diagram of a gaming system 2600,
according to an example embodiment. FIG. 9 shows a block diagram of
a gaming system 2600 in accordance with the described embodiments.
The gaming system 2600 can include one or more servers, such as
server 2602, and a variety of gaming devices including but not
limited to table gaming devices, such as 2652, mobile gaming
devices, such as 2654, and slot-type gaming devices, such as 2656.
The table gaming devices, such as 2652, can include apparatus
associated with table games where a live operator or a virtual
operator is employed. The gaming devices and one or more servers
can communicate with one another via a network 2601. The network
can include wired, wireless or a combination of wired and wireless
communication connections and associated communication routers.
[0040] Some gaming devices, such as 2652, 2654 and 2656, can be
configured with a player interface that allows at least 1)
selections, such as a wager amount, associated with a wager-based
game to be made and 2) an outcome of the wager-based game to be
displayed. As an example, gaming devices, 2652, 2654 and 2656,
include player interfaces, 2652a, 2654a and 2656a, respectively.
Typically, gaming devices with a player interface are located in
publically accessible areas, such as a casino floor. On the other
hand, some gaming devices, such as server 2602, can be located in
publically inaccessible areas, such is in a back-room of a casino
or even off-site from the casino. Gaming devices located in
publically inaccessible areas may not include a player interface.
For instance, server 2602 does not include a player interface.
However, server 2602 includes an administrator interface 2635 that
allows functions associated with the server 2602 to be
adjusted.
[0041] An example configuration of a gaming device is described
with respect to gaming device 2604. The gaming device 2604 can
include 1) a game controller 2606 for controlling a wager-based
game played on the gaming device and 2) a player interface 2608 for
receiving inputs associated with the wager-based game and for
displaying an outcome to the wager-based game. In more detail, the
game controller 2606 can include a) one or more processors, such as
2626, b) memory for holding software executed by the one or more
processors, such as 2628, c) a power-hit tolerant memory, such as
2630, d) one or more trusted memories, such as 2632, e) a random
number generator and f) a plurality of software applications, 2610.
The other gaming devices, including table gaming device 2652,
mobile gaming device 2654, slot-type gaming device 2656 and server
2602, can each include a game controller with all or a portion of
the components described with respect to game controller 2606.
[0042] In particular embodiments, the gaming device can utilize a
"state" machine architecture. In a "state" machine architecture
critical information in each state is identified and queued for
storage to a persistent memory. The architecture doesn't advance to
the next state from a current state until all the critical
information that is queued for storage for the current state is
stored to the persistent memory. Thus, if an error condition occurs
between two states, such as a power failure, the gaming device
implementing the state machine can likely be restored to its last
state prior to the occurrence of the error condition using the
critical information associated with its last state stored in the
persistent memory. This feature is often called a "roll back" of
the gaming device. Examples of critical information can include but
are not limited to an outcome determined for a wager-based game, a
wager amount made on the wager-based game, an award amount
associated with the outcome, credits available on the gaming device
and a deposit of credits to the gaming device.
[0043] The power-hit tolerant memory 2630 can be used as a
persistent memory for critical data, such as critical data
associated with maintaining a "state" machine on the gaming device.
One characteristic of a power-hit tolerant memory 2630 is a fast
data transfer time. Thus, in the event of a power-failure, which
might be indicated by a sudden power fluctuation, the critical data
can be quickly loaded from volatile memory, such as RAM associated
with the processor 2626, into the power-hit tolerant memory 2630
and saved.
[0044] In one embodiment, the gaming device 2605 can be configured
to detect power fluctuations and in response, trigger a transfer of
critical data from RAM to the power-hit tolerant memory 2630. One
example of a power-hit tolerant memory 2630 is a battery-backed
RAM. The battery supplies power to the normally volatile RAM so
that in the event of a power failure data is not lost. Thus, a
battery-backed RAM is also often referred to as a nonvolatile RAM
or NV-RAM. An advantage of a battery-backed RAM is that the fast
data transfer times associated with a volatile RAM can be
obtained.
[0045] The trusted memory 2632 is typically a read-only memory of
some type that may be designed to be unalterable. An EPROM or
EEPROM are two types of memory that can be used as a trusted memory
2632. The gaming device 2604 can include one or more trusted
memories.
[0046] Prior to installation the contents of a trusted memory, such
as 2632, can be verified. For instance, a unique identifier, such
as a hash value, can be generated on the contents of the memory and
then compared to an accepted hash value for the contents of the
memory. The memory may not be installed if the generated and
accepted hash values do not match. After installation, the gaming
device can be configured to check the contents of the trusted
memory. For instance, a unique identifier, such as a hash value,
can be generated on contents of the trusted memory and compared to
an expected value for the unique identifier. If the generated value
of the unique identifier and the expected value of the unique
identifier don't match, then an error condition can be generated on
the gaming device 2604. In one embodiment, the error condition can
result in the gaming device entering a tilt state where game play
is temporarily disabled on the gaming device.
[0047] Sometimes verification of software executed on the gaming
device 2604 can be performed by a regulatory body, such as a
government agency. Often software used by a game controller, such
as 2606, can be highly regulated, where only software approved by a
regulatory body is allowed to be executed by the game controller
2606. In one embodiment, the trusted memory 2632 can store
authentication programs and/or authentication data for
authenticating the contents of various memories on the gaming
device 2604. For instance, the trusted memory 2632 can store an
authentication program that can be used to verify the contents of a
mass storage device, such as 2620, which can include software
executed by the game controller 2606.
[0048] The random number generator (RNG) 2634 can be used to
generate random numbers that can be used to determine outcomes for
a game of chance played on the gaming device. For instance, for a
mechanical or video slot reel type of game, the RNG, in conjunction
with a paytable that lists the possible outcomes for a game of
chance and the associated awards for each outcome, can be used to
generate random numbers for determining reel positions that display
the randomly determined outcomes to the wager-based game. In other
example, the RNG might be used to randomly select cards for a card
game. Typically, as described above, the outcomes generated on a
gaming device, such as 2604, are considered critical data. Thus,
generated outcomes can be stored to the power-hit tolerant memory
2630.
[0049] Not all gaming devices may be configured to generate their
own game outcomes and thus, may not use an RNG for this purpose. In
some embodiments, game outcomes can be generated on a remote
device, such as server 2602, and then transmitted to the gaming
device 2604 where the outcome and an associated award can be
displayed to the player via the player interface 2608. For
instance, outcomes to a slot-type game or a card game can be
generated on server 2602 and transmitted to the gaming device
2604.
[0050] In other embodiments, the gaming device 2604 can be used to
play central determination games, such as bingo and lottery games.
In a central determination game, a pool of game outcomes can be
generated and then, particular game outcomes can be selected as
needed (e.g., in response to a player requesting to play the
central determination game) from the pool of previously generated
outcomes. For instance, a pool of game outcomes for a central
determination game can be generated and stored on server 2602.
Next, in response to a request to play the central determination
game on gaming device 2604, one of the outcomes from the pool can
be downloaded to the gaming device 2604. A game presentation
including the downloaded outcome can be displayed on the gaming
device 2604.
[0051] In other embodiments, thin client type gaming devices, such
as mobile gaming devices used to play wager-based video card or
video slot games, may be configured to receive at least game
outcomes from a remote device and not use an RNG to generate game
outcomes locally. The game outcomes can be generated remotely in
response to inputs made on the mobile device, such as an input
indicating a wager amount and/or an input to initiate the game.
This information can be sent from the mobile device to a remote
device, such as from mobile gaming device 2654 to server 2602.
After receiving the game outcome from the remote device, a game
presentation for the game outcomes generated remotely can be
generated and displayed on the mobile device. In some instances,
the game presentation can also be generated remotely and then
streamed for display to the mobile device.
[0052] The game controller 2606 can be configured to utilize and
execute many different types of software applications 2610.
Typically, the software applications utilized by the game
controller 2606 can be highly regulated and may undergo a lengthy
approval process before a regulatory body allows the software
applications to be utilized on a gaming device deployed in the
field, such as in a casino. One type of software application the
game controller can utilize is an Operating System (OS). The OS can
allow various programs to be loaded for execution by the processor
2626, such as programs for implementing a state machine on the
gaming device 2606. Further, the OS can be used to monitor resource
utilization on the gaming device 2606. For instance, certain
applications, such as applications associated with game outcome
generation and game presentation that are executed by the OS can be
given higher priority to resources, such as the processor 2626 and
memory 2628, than other applications that can be executing
simultaneously on the gaming device.
[0053] As previously described, the gaming device 2604 can execute
software for determining the outcome of a wager-based game and
generating a presentation of the determined game outcome including
displaying an award for the game. As part of the game outcome
presentation one or more of 1) electro-mechanical devices, such as
reels or wheels, can be actuated, 2) video content can be output to
video displays, 3) sounds can be output to audio devices, 4) haptic
responses can be actuated on haptic devices or 5) combinations
thereof, can be generated under control of the game controller
2606. The peripheral devices used to generate components of the
game outcome presentation can be associated with the player
interface 2608 where the types of devices that are utilized for the
player interface 2608 can vary from device to device.
[0054] To play a game, various inputs can be required. For
instance, via input devices coupled to the gaming device 2604, a
wager amount can be specified, a game can be initiated or a
selection of a game choice associated with the play of the game can
be made. The software 2610 executed by the game controller 2606 can
be configured to interpret various signals from the input devices,
such as signals received from a touch screen controller or input
buttons, and affect the game played on the gaming device in
accordance with the received input signals. The input devices can
also be part of the player interface 2608 provided with the gaming
device, such as 2604.
[0055] In other embodiments, the gaming software 2610 executed by
the game controller 2606 can include applications that allow a game
history including the results of a number of past games to be
stored, such as the previous 10 or 100 games played on the gaming
device 2604. The game history can be stored to a persistent memory
including but not limited to the power-hit tolerant memory 2630.
The gaming controller 2606 can configured to provide a menu
(typically, only operator accessible), that allows the results of a
past game to be displayed via the player interface 2608. The output
from the history menu can include a re-creation of the game
presentation associated with a past game outcome, such as a video
representation of card hand associated with a video poker game, a
video representation of a reel configuration associated with a
video slot game, and/or raw data associated with the past game
result, such as an award amount, an amount wagered, etc. The
history menu can be used for dispute resolution purposes, such as
if a player complains that they have not been properly awarded for
a game previously played on the gaming device 2604.
[0056] The reporting software can be used by the game controller
2606 to report events that have occurred on the gaming device 2604
to remote device, such as server 2602. For instance, in one
embodiment, the game controller 2606 can be configured to report
error conditions that have been detected on the gaming device 2604,
such as if a device has malfunctioned or needs attention. For
instance, the reporting software can be used to send a message from
the gaming device 2604 to the server 2602 indicating that a printer
on the gaming device needs a refill of tickets. In another
embodiment, the gaming controller 2606 can be configured to report
security events that may have occurred on the gaming device 2604,
such as but not limited to if a door is opened, a latch is
activated or an interior portion of the gaming device 2604 has been
accessed.
[0057] In yet other embodiments, the game controller 2606 can be
configured to report gaming activity and associated events that has
been generated on the gaming device, such as a deposit of cash or
an indicia of credit, at the gaming device, a generation of game
outcome including an associated award amount and a dispensation of
cash or an indicia of credit from the gaming device 2604. As part
of a loyalty program, the gaming activity can be associated with a
particular player. The reporting software can include player
tracking elements that allow the gaming activity of a particular
player to be reported to a remote device, such as server 2602.
[0058] The game controller 2606 can execute the authentication
software to verify the authenticity of data and/or software
programs executed on the gaming device 2604. For instance, the
authentication software can be used to verify the authenticity of
data and/or software applications when they are first downloaded to
the gaming device 2604. Further, the authentication software can be
used to periodically verify the authenticity of data and/or
software applications currently residing on the gaming device, such
as software applications stored on one of the memories coupled to
the gaming device 2604 including applications loaded into the
memory 2628 for execution by the processor 2626.
[0059] The communication software executed by the game controller
2606 can be used to communicate with a variety of devices remote to
the gaming device 2604. For instance, the communication software
can be used to communicate with one or more of a) servers remote to
the device, such as 2602, b) other gaming devices, such as table
gaming device 2652, mobile gaming device 2654 and slot-type gaming
device 2656 and c) mobile devices carried by casino personnel or
players in the vicinity of the gaming device 2604. Via the
communication software, the game controller can be configured to
communicate via many different communication protocols. For
instance, different wireless and/or wired communication protocols
can be implemented. Further, proprietary or non-proprietary gaming
specific protocols can be implemented. For instance, gaming
specific non-proprietary communication protocols, such as G2S (game
to system), GDS (gaming device standard) and S2S (system to system)
communication protocols provided by the Gaming Standards
Association (GSA), Fremont, Calif., can be implemented on the
gaming devices described herein.
[0060] The gaming device 2604 can communicate with one or more
remote devices via one or more network interfaces, such as 2612.
For instance, via network interfaces 2612 and the network 2601, the
gaming device 2604 can communicate with other gaming devices, such
as server 2602 and/or gaming devices, 2652, 2654 and 2656. The
network interfaces can provide wired or wireless communications
pathways for the gaming device 2604. Some gaming devices may not
include a network interface or can be configured to operate in a
stand-alone mode where the network interface is not connected to a
network.
[0061] In other embodiments, a mobile device interface or
interfaces, such as 2614, can be provided for communicating with a
mobile device, such as a cell phone or a tablet computer carried by
players or casino personnel temporarily in the vicinity of the
gaming device 2604. A wireless communication protocol, such as
Bluetooth.TM. and a Wi-Fi compatible standard, can be used for
communicating with the mobile devices via the mobile device
interfaces 2614. In one embodiment, the mobile device interface can
implement a short range communication protocol, such as a
near-field communication (NFC) protocol used for mobile wallet
applications. NFC is typically used for communication distances of
4 cm or less. In addition, a wired communication interface, such as
a docking station, can be integrated into the gaming device, such
as 2604. The wired communication interface can be configured to
provide communications between the gaming device 2604 and the
mobile device and/or providing power to the mobile device.
[0062] The gaming device 2604 can include one or more each of value
input devices 2616 and value output device 2618. The value input
devices 2616 can be used to deposit cash or indicia of credit onto
the gaming device. The cash or indicia of credit can be used to
make wagers on games played on the gaming device 2604. Examples of
value input devices 2616 include but are not limited to a
magnetic-striped card or smart card reader, a bill and/or ticket
acceptor, a network interface for downloading credits from a remote
source, a wireless communication interface for reading credit data
from nearby devices and a coin acceptor. A few examples of value
input devices are shown in FIG. 5.
[0063] The value output devices can be used to dispense cash or
indicia of credit from the gaming device 2604. Typically, the
indicia of credit can be exchanged for cash. For instance, the
indicia of credit can be exchanged at a cashier station or at a
redemption station. Examples of value output devices can include a
network interface for transferring credits into a remote account, a
wireless communication interface that can be used with a mobile
device implementing mobile wallet application, a coin hopper for
dispensing coins or tokens, a bill dispenser, a card writer, a
printer for printing tickets or cards redeemable for cash or
credits. Another type of value output device is a merchandise
dispenser, which can be configured to dispense merchandise with a
tangible value from a gaming device. A few examples of value output
devices are shown in FIG. 5.
[0064] The combination of value input devices 2616 and value output
devices 2618 can vary from device to device. In some embodiments, a
gaming device 2604 may not include a value input device or a value
output device. For instance, a thin-client gaming device used in a
mobile gaming application may not include a value input device and
a value output device. Instead, a remote account can be used to
maintain the credits won or lost from playing wagerbased games via
the mobile device. The mobile device can be used to access the
account and affect the account balance via game play initiated on
the mobile device. Credits can be deposited or withdrawn from the
remote account via some mechanism other than via the mobile device
interface.
[0065] In yet other embodiments, the gaming device 2604 can include
one or more secondary controllers 2619. The secondary controllers
can be associated with various peripheral devices coupled to the
gaming device, such as the value input devices and value output
devices described in the preceding paragraphs. As another example,
the secondary controllers can be associated with peripheral devices
associated with the player interface 2608, such as input devices,
video displays, electro-mechanical displays and a player tracking
unit. In some embodiments, the secondary controllers can receives
instructions and/or data from and provide responses to the game
controller 2606. The secondary controller can be configured to
interpret the instructions and/or data from the game controller
2606 and control a particular device according to the received
instructions and/or data. For instance, a print controller may
receive a print command with a number of parameters, such as a
credit amount and in response print a ticket redeemable for the
credit amount. In another example, a touch screen controller can
detect touch inputs and send information to the game controller
2606 characterizing the touch input.
[0066] In a particular embodiment, a secondary controller can be
used to control a number of peripheral devices independently of the
game controller 2606. For instance, a player tracking unit can
include one or more of a video display, a touch screen, card
reader, network interface or input buttons. A player tracking
controller can control these devices to provide player tracking
services and bonusing on the gaming device 2604. In alternate
embodiments, the game controller 2604 can control these devices to
perform player tracking functions. An advantage of performing
player tracking functions via a secondary controller, such as a
player tracking controller, is that since the player tracking
functions don't involve controlling the wager-based game, the
software on the player tracking unit can be developed modified via
a less lengthy and regulatory intensive process than is required
for software executed by the game controller 2606, which does
control the wager-based game. In general, using a secondary
controller, certain functions of the gaming device 2604 that are
not subject to as much regulatory scrutiny as the game play
functions can be decoupled from the game controller 2606 and
implemented on the secondary controller instead. An advantage of
this approach, like for the player tracking controller, is that
software approval process for the software executed by the
secondary controller can be less intensive than the process needed
to get software approved for the game controller.
[0067] A mass storage unites) 2620, such as a device including a
hard drive, optical disk drive, flash memory or some other memory
storage technology can be used to store applications and data used
and/or generated by the gaming device 2604. For instance, a mass
storage unit, such as 2620, can be used to store gaming
applications executed by the game controller 2606 where the gaming
device 2604 can be configured to receive downloads of game
applications from remote devices, such as server 2602. In one
embodiment, the game controller 2606 can include its own dedicated
mass storage unit. In another embodiment, critical data, such as
game history data stored in the power-hit tolerant memory 2630 can
be moved from the power-hit tolerant memory 2630 to the mass
storage unit 2620 at periodic intervals for archival purposes and
to free up space in the power-hit tolerant memory 2630.
[0068] The gaming device 2604 can include security circuitry 2622,
such as security sensors and circuitry for monitoring the sensors.
The security circuitry 2622 can be configured to operate while the
gaming device is receiving direct power and operational to provide
game players well as when the gaming device is uncoupled from
direct power, such as during shipping or in the event of a power
failure. The gaming device 2604 can be equipped with one or more
secure enclosures, which can include locks for limiting access to
the enclosures. One or more sensors can be located within the
secure enclosures or coupled to the locks. The sensors can be
configured to generate signals that can be used to determine
whether secure enclosures have been accessed, locks have been
actuated or the gaming device 2604, such as a mobile device has
been moved to an unauthorized area. The security monitoring
circuitry can be configured to generate, store and/or transmit
error events when the security events, such as accessing the
interior of the gaming device, have occurred. The error events may
cause the game controller 2606 to place itself in a "safe" mode
where no game play is allowed until the error event is cleared.
[0069] The server 2602 can be configured to provide one or more
functions to gaming devices or other servers in a gaming system
2600. The server 2602 is shown performing a number of different
functions. However, in various embodiments, the functions can be
divided among multiple servers where each server can communicate
with a different combination of gaming devices. For instance,
player interface support 2636 and gaming device software 2638 can
be provided on a first server, progressives can be provided on a
second server, loyalty program functions 2640 and accounting 2648
can be provided on a third server, linked gaming 2644 can be
provided on a fourth server, cashless functions 2646 can be
provided on a fifth server and security functions 2650 can be
provided on a sixth server. In this example, each server can
communicate with a different combination of gaming devices because
each of the functions provided by the servers may not be provided
to every gaming device in the gaming system 2600. For instance, the
server 2602 can be configured to provide progressive gaming
functions to gaming devices 2604, 2652 and 2656 but not gaming
device 2654. Thus, the server 2602 may not communicate with the
mobile gaming device 2654 if progressive functions are not enabled
on the mobile gaming device at a particular time.
[0070] Typically, each server can include an administrator
interface that allows the functions of a server, such as 2602, to
be configured and maintained. Each server 2602 can include a
processor and memory. In some embodiments, the servers, such as
2602, can include a game controller with components, such as but
not limited to a power-hit tolerant memory 2630, a trusted memory
2632 and an RNG 2634 described with respect to gaming device 2604.
The servers can include one or more network interfaces on which
wired or wireless communication protocols can be implemented. Next,
some possible functions provided by the server 2602 are described.
These functions are described for the purposes of illustration only
and are not meant to be limiting.
[0071] The player interface support 2636 can be used to serve
content to gaming devices, such as 2604, 2652, 2654 and 2656,
remote to the server. The content can include video and audio
content that can be output on one of the player interfaces, such as
2608, 2652a, 2654a and 2656a. Further, the content can be
configured to utilize unique features of a particular player
interface, such as video displays, wheels or reels, if the
particular player interface is so equipped.
[0072] In one embodiment, via the player interface support, content
can be output to all or a portion of a primary video display that
is used to output wager-based game outcomes on a player interface
associated with a gaming device. For instance, a portion of the
primary display can be allocated to providing a "service window" on
the primary video display where the content in the service window
is provided from a server remote to the gaming device. In
particular embodiments, the content delivered from the server to a
gaming device as part of the player interface support 2636 can be
affected by inputs made on the gaming device. For instance, the
service window can be generated on a touch screen display where
inputs received via the service window can be sent back to server
2602. In response, to the received inputs, the server 2602 can
adjust the content that is displayed on the remote gaming device
that generated the inputs.
[0073] If a player's identity is known, then the player interface
support 2636 can be used to provide custom content to a remote
gaming device, such as 2604. For instance, a player can provide
identification information, such as information indicating their
membership in a loyalty program, during their utilization of a
gaming device. The custom content can be selected to meet the
identified player's interests. In one embodiment, the player's
identity and interests can be managed via a loyalty program, such
as via a loyalty program account associated with loyalty function
2640. The custom content can include notifications, advertising and
specific offers that are determined to be likely of interest to a
particular player.
[0074] The gaming device software function 2638 can be used to
provide downloads of software for the game controller and/or second
controllers associated with peripheral devices on a gaming device.
For instance, the gaming device software 2638 may allow an operator
and/or a player to select a new game for play on a gaming device.
In response to the game selection, the gaming device software
function 2638 can be used to download game software that allows a
game controller to generate the selected game. In another example,
in response to determining that a new counterfeit bill is being
accepted by bill acceptors in the gaming system 2600, the gaming
device software function 2638 can be used to download a new
detection algorithm to the bill acceptors that allow the
counterfeit bill to be detected.
[0075] The progressive gaming function 2642 can be used to
implement progressive game play on one or more gaming devices. In
progressive game play, a portion of wagers associated with the play
of a progressive game is allocated to a progressive jackpot. A
group of gaming devices can be configured to support play of the
progressive game and contribute to the progressive jackpot. In
various embodiments, the gaming devices contributing to a
progressive jackpot may be a group of gaming devices collocated
near one another, such as a bank of gaming machines on a casino
floor, a group of gaming devices distributed throughout a single
casino, or group of gaming devices distributed throughout multiple
casinos (e.g., a wide area progressive). The progressive gaming
function 2642 can be used to receive the jackpot contributions from
each of the gaming devices participating in the progressive game,
determine a current jackpot and notify participating gaming devices
of the current progressive jackpot amount, which can be displayed
on the participating gaming devices if desired.
[0076] The loyalty function 2640 can be used to implement a loyalty
program within a casino enterprise. The loyalty function 2640 can
be used to receive information regarding activities within a casino
enterprise including gaming and non-gaming activities and associate
the activities with particular individuals. The particular
individuals can be known or may be anonymous. The loyalty function
2640 can used to store a record of the activities associated with
the particular individuals as well as preferences of the
individuals if known. Based upon the information stored with the
loyalty function 2640 comps (e.g., free or discounted services
including game play), promotions and custom contents can be served
to the particular individuals.
[0077] The linked gaming function 2644 can be used to used provide
game play activities involving player participating as a group via
multiple gaming devices. An example, a group of player might be
competing against one another as part of a slot tournament. In
another example, a group of players might be working together in
attempt to win a bonus that can be shared among the players.
[0078] The cashless function 2646 can enable the redemption and the
dispensation of cashless instruments on a gaming device. For
instance, via the cashless function, printed tickets, serving as a
cashless instrument, can be used to transfer credits from one
gaming device to another gaming device. Further, the printed
tickets can be redeemed for cash. The cashless function can be used
to generate identifying information that can be stored to a
cashless instrument, such as a printed ticket, that allows the
instrument to later be authenticated. After authentication, the
cashless instrument can be used for additional game play or
redeemed for cash.
[0079] The accounting function can receive transactional
information from various gaming devices within the gaming system
2600. The transactional information can relate to value deposited
on each gaming device and value dispensed from each gaming device.
The transactional information, which can be received in real-time,
can be used to assess the performance of each gaming device as well
as an overall performance of the gaming system. Further, the
transactional information can be used for tax and auditing
purposes.
[0080] The security function 2650 can be used to combat fraud and
crime in a casino enterprise. The security function 2650 can be
configured to receive notification of a security event that has
occurred on a gaming device, such as an attempt at illegal access.
Further, the security function 2650 can receive transactional data
that can be used to identify if gaming devices are being utilized
in a fraudulent or unauthorized manner. The security function 2650
can be configured to receive, store and analyze data from multiple
sources including detection apparatus located on a gaming device
and detection apparatus, such as cameras, distributed throughout a
casino. In response to detecting a security event, the security
function 2650 can be configured to notify casino personnel of the
event. For instance, if a security event is detected at a gaming
device, a security department can be notified. Depending on the
security event, one or more team members of the security department
can be dispatched to the vicinity of the gaming device. Next, a
perspective diagram of a slot-type gaming device that can include
all or a portion of the components described with respect to gaming
device 2604 is described.
